VALVE.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed January 14, 1914. Serial No. 811,991.

To all whom it may concern Be it known that I, BURTON J. HINE, a citizenof the United States, residing at Vaterbury, county of New Haven, andState of Connecticut, have invented certain new and useful Improvementsin Valves, fully described and represented in the followingspecilication and the accompanying drawings, forming a part of thesaine.

This invention relates to improvements in valves, and partici'ilarly tomeans for packing the valve stems of underground valves.

The object of the invention is to provide a valve and post constructionsuch that when the valve is buried in the ground, the packing gland forthe valve stem may be repacked without the necessity of digging up orotherwise disturbing the valve itself.

With this general object in view, the invention consists in thefeatures, details of construction and combination of parts which willfirst be described in connection with the accompanying d'awings and thenparticularly pointed out.

In the drawings-Figure l is a vertical sectional view, partly inelevation, of one embodiment of the invention; Fig. 2 a horizontalsection on the line 2-2, Fig. l; Fig. 3 a detail vertical section in aplane at right angles to that of Fig. l; Fig. 1l a detail view oit amodified form of stuilingbox; and Fig. 5 a detail view illustrating theembodiment of the new packing device in a street box.

Referring to the drawings, l indicates any well known form of valve bodyarranged to be buried in the ground or otherwise so placed as to beinaccessible. In the illus tration, the valve is supposed to be agatevalve and is shown as inserted in a watermain, parts of which areindicated at 2. The valve body is illustrated as broken away in order toshow the valve indicated at 3, the stem ot the valve being indicated at4, this stem projecting through a bonnet 5 suitably secured to the valvebody, as by providing the bonnet with a flange bolted to a correspondingflange on the valve body. To the bonnet is secured a barrel or casing 6,whose upper end extends to a point remote from the valve body, as forexample to a point above the surface of the ground so that access may behad conveniently to such outer or upper end of the casino.

In the best embodiment of the invention, the casing is flanged at itsinner end and the bonnet is flanged at its outer end, the two `flangesbeing connected by bolts as will be clear from the dri'iwings.

suitable packing device is provided for the valve stem, this packingdevice being adjacent to the valve body. The packing device comprisestwo parts, one oi which serves as a stalling box and the other as agland arranged to enter the stuiling box, the space within the stallingbox being arranged to receive any suitable kind of packinef.

In the best embodiment of the invention, one of the two parts oi. thepacking device 1s secured to the valve body, as ior example by attachingit to the bonnet, and the other part `is connected to a means forremoving and replacing said part, this means eX- tending to a pointremote from the valve body, as for example to a point above the surfaceof the ground. In the preferred embodiment of the invention illustratediii the drawings, the gland is secured to the 'ialve body and thestuiling box is removable from the surface of the ground. In such aconstruction, the gland indicated at 7 may be provided with a flangewhich is secured to the outer Iiange of the bonnet, as for example bymeans of bolts. The stalling box indicated at 8 is suitably attached tothe means for removing and replacing it, this means in the presentexample consisting of a hollow stulling box stem indicated at 9, whichmay be a piece ot' ordinary pipe. In the example illustrated, thestalling box may have its outer end inserted in the stufling box steinand secured thereto by means oit' a pin as indicated at l0, the stallingbox having a shoulder indicated at 1l extending.

beyond the stalling box stem.

For the purpose ol insuring the retention of the packing within thechamber in the stuffing box, suitable means may be provided. In thepresent example of the invention, this means may consist ol a ribindicated at 19. located intermediate oi the two ends of the stallingbox chamber, so that when the packing is compressed in said chamber therib 12 will engage the packing and prevent it from dropl'iingi'eadilyfrom the stulling box. Instead oi one rib only as shown in Fig. 1, aplurality oi such vribs may be employed, and the ribs may be inclined tothe axis of the stuffing box and merged into the form of a screw thread,as indicated at 12, Fig. L1.

An important feature of this invention consists in locating the meansfor compressing the packing at a point remote from the valve body. lnthe best embodiment of the invention, this means is located at a pointreadily accessible, as for example at the outer end of the stuffing boxstem, which is usually above the surface of the ground. Tn the exampleillustrated, this means for compressing the packing comprises anadjusting gland 13 which bears upon the outer end of the stuiiing boxstem and is connected to the casing 6 by suitable bolts indicated at1li. The upper end of the casing may be provided with an inwardextending flange for the reception of said bolts. The valve stem isarranged to be operated from a point remote from the valve body, themeans for doing this being such as to be readily detachable from thevalve stem. ln the present example, the outer end of the valve stem istapered and is arranged to be received in a correspondingly shapedsocket piece 15 attached to the lower end of an extension valve rod 16,which extends to a considerable distance above the surface of theground. For the purpose of protecting the parts above ground, anysuitable means may be employed. 1n the present example, this means isshown as comprising an indicator post 17 which carries at its upper endthe vusual indicator and indicator-operating mechanism arranged to workin connection with the extension valve rod in any of the well knownways. As this indicator mechanism constitutes no part of the presentinvention, it need not be described in detail. The lower part of theindicator post is made of such diameter as to set over the upper end ofthe casing 6 and, for the purpose of locking the post to said casing,the post is provided preferably at opposite sides with slots throughwhich extend ears 18 projecting radially from the casing. The indicatorpost is also provided with any suitable fastening devices,for example,the machine screws 19, which are threaded through openings in the postand are ai'- ranged to bear against the projecting end of the case.

The operation of this device is obvious, but may be briefly described asfollows: lllhen it is desired to repack the valve stem, the screws 19are loosened and the post is lifted directly upward. rThe extensionvalve rod, which is connected to the indicator post by the indicatormechanism at the upper end, moves upward with the post, leaving thevalve stem. The hole in the adjusting gland 13 is large enough to allowthe socket piece 15 to pass through it, thus allowing the indicatorpost, the extension valve red and said gland to be removed from theremainfact that said packing is held by the packing retaining device,such as the rib 12, F ig.

1, or the ribs 12, F ig. 4. The packing may now be removed, ifnecessary. To put in a new packing, it is only necessary to insertthrough the stiiiling box a rod of cross` section having the same, orpreferably a larger, diameter .than that of the valve stem. The newpacking may be inserted in the stufing box chamber around this rod andpacked in tightly in the same manner as if the valve stem itself were inplace in said stufling box. As soon as the packing has been properlyplaced in its chamber, the rod may be withdrawn, thereby leaving a holeof suitable size for the reception of the valve stem. Then, the stuffingbox may be slid down in the casing 6 by a proper manipulation of thestuliing box stem so that the valve stem passes through the hole in thepacking and through the stuing box, the gland entering the lower end ofthe stuiling box chamber and'contacting with the packing. The adjustinggland may then be brought to bear against the upper end of said stuliingbox stein and the nuts screwed down upon'their respectivebolts lll toforce the adjusting gland against the upper end of the stu'lling boxstem and thereby to force the stuliing box toward the gland. Thisresults in compressing the packing around the valve stem. As soon as theproper adjustment of the adjusting gland has been made, the indicatorpost may be slipped down over the projecting end of the case, the socket15 at the lower end of the extension valve rod thereby engaging thetapered outer end of the valve stem. The screws 19 may then betightened, thus completing the operation. It will be seen that byrotating the upper end of the extension valve rod, the valve may beoper` ated as desired. 1t is to be noted that by this improved packingdevice, it is uiinecessary to dig down for the purpose of packing thevalve stein, and furthermore, the valve stem may be packed from aboveground, whetl er the valve be opened or closed. This feature is of greatimportance in connection with gate-valves for ire-systems,.because itrenders unnecessary the shutting off of the water during the packingoperation.

The improved means for packing the stem of an underground valve may beap lied in a modified form to a street box. glich an embodiment of Vtheinvention necessitates that the casing shall terminate substantiallyflush with the street surface. Such a structure is illustrated in Fig. 5where the casing 6 is provided with a socket end 6a terminating at thestreet level, vthis socket being arranged to receive a cap 21 which maybe readily removed. The extension valve rod indicated at 16 'terminatesjust below the cap and is provided with a squared end for the receptionof a wrench. In other respects, the construction oi' the partsillustrated is substantially the same as was described in connectionwith Figs. 1 to 8. Upon removing the cap, the valve may be operated bymeans of a wrench applied to the upper end ot' the same valve stem in awell known manner. 1n order to repack the stu'tiing box the adjustinggland 13 is removed and thereupon the stuffing box stem may be drawn up,together with the s'tuliing box. The packing may be replaced ashereinbefore described in connection with the structure shown in Fig. 1.Thereupon, the stufting box is replaced and the adjusting j gland 13 putin place and screwed down by means of the bolts 111 to the desiredextent.
